12" Powerbook for Gaming ? ? ?

I realy like the size/weight/form factor of the 12" but I've heard that because it does'nt have L3 cache, some newer games won't run on it. Is that true?

Gaming is not the main reason I'm about to buy a new laptop. But I do travel a lot for work and sometime I get bored on the plane or at the hotel. Games would be a big plus. For how long do you think the 12" powebook will be fitting in the new games "minimum requirements" window?
